A technical patent drawing of a pinball machine dominates this composition, rendered in black ink on a white ground with the word "PINBALL" anchored at the top. The diagram explodes outward in an intricate web of mechanical components, numbered callouts, and cross-sectional views that reveal the ingenious engineering beneath the game's surface, capturing both the complexity and the playful spirit of mid-century arcade artwork. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
